Specification of Letters Patent.

Patented March 20, 1906.

Application filed October 12, 1905. Serial No. 282,406.

This invention has relation to pipewrenches; and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to providea wrench for pipework which will easily and rapidly grip' the ipe, is simple and cheap in construction, and which can be folded up into compact form when not in use inorder that it may take up but little space in tool-kit or for shipping purposes.

In the accompanying drawings, Figure 1 is a perspective View of the wrenc Fig. 2 is a longitudinal sectional view of the same.

The Wrench consists ofthe handle 1, which is provided with the lug 2. The working end of the handle 1 is rovided with the integral bifurcations 3 3, w 'ch are provided on their faces with the ratchet-teeth 4. The said bifurcations are slightly curved or concaved along their longitudinal axes, as shown in Fig. 2. The extreme outer ends of the bifurcations 3 3 are provided with the integral shoulders 5, which extend substantially at right angles to the longitudinal axes of the said bifurcations. The cross-bar 6 connects the said bifurcations and is riveted to the same, as indicated at 7 in Fig. 2.

The jaws 8 8 are pivoted at their lower ends to the lug 2 and are slightly curved or concaved along their longitudinal axes. The inner faces of the said jaws are provided with the ratchet-teeth 9. The link 10 is pivoted .at one end between the outer ends of the jaws 8 and is rovided along its under surface with the ratchet-teeth 11, which are adapted to engage the cross-bar 6 in amanner as indicated in both-figures of the drawings. The said link 10 is slightly curved or concaved along its longitudinal axis.

The operation of the wrench is as follows: The pipe is inserted between, the ratchetfaces 4 of the bifurcations 3, and the ratchetfaces 9 of the jaws 8 are then swung toward the bifurcations 3 until the ratchet-faces of both the said jaws and the said bifurcations come in contact with the sides of the pipe.

The link 10 is then thrown over, and one of its ratchets engages the edge of the cross-bar 6. The free end of the handle may then be swung around in the usual manner and the pipe is turned. 4

It is obvious that a wrench of one size may be used upon several difierent sizes of pipe, although a wrench of this construction may be made indifferent sizes to accommodate different classes of pipework. It is also obvious that by turning thewrench over it may also be used for unscrewing the pipe.

Having described my lnvention, what I claim as new, and desire to secure by Letters Patent, is

1. A wrench consisting of a handle having at one end integral bifurcations provided with ratchet-teeth surfaces, a cross-bar. connecting said bifurcations together, 'aws pivotedto said handle and havmg ratc et-teeth surfaces, a link pivoted at one end between said jaws and having ratchet-teeth adapted to engage said cross-bar.

2. A wrench consisting ofa handle having at one end integral bifurcations provided with ratchet-teeth surfaces and being curved along their longitudinal axes, a cross-bar connecting said bifurcations together, jaws pivoted to said handle and having ratchet-teeth surfaces and being curved along their longi tudinal axes, a link ivoted at one end between said jaws an having ratchet-teeth adapted to engage said cross-bar and being curved along its longitudinal axis.

3. A wrench consisting of a handle having at one end integral bifurcations provided with ratchet-teeth surfaces, said bifurcations having their extreme ends bent at an angle to their longitudinal axes, a cross-bar attached to said bifurcations under the bent ends thereof, aws pivoted to said handle, and having. ratchet-teeth surfaces, a link pivoted at one end between said jaws and having ratchet-
